Europe approves SES purchase of Intelsat

9:00 am

The European Commission has now approved the purchase of the long established satellite communications company Intelsat by the long established Luxembourg satellite communications company SES for about $4 billion.

This decision follows an approval by the government of the United Kingdom. It now appears the only remaining regulatory hurdle is approvals by the FCC and the Department of Justice in the U.S.

This buy-out follows similar mergers by other old established satellite companies, such as the merger of Viasat with Imarsat and OneWeb with Eutelsat. All are occurring because these older companies, which mostly launched large geosynchronous satellites, have been under heavy competitive pressure from the low orbit constellations like Starlink and OneWeb.

Whether these older companies can compete following these mergers however remains uncertain. To succeed they need to have a product customers want, and at the moment it isn’t clear they have one.

Axiom’s fourth commercial manned mission scrubbed due to leak

8:04 pm

Axiom and SpaceX have scrubbed the launch tomorrow of Axiom’s fourth commercial manned mission to ISS due to an oxygen leak detected during the standard prelaunch static fire test.

NASA, Axiom Space, and SpaceX are standing down from the launch opportunity on Wednesday, June 11, of Axiom Mission 4 to the International Space Station to allow additional time for SpaceX teams to repair a liquid oxygen leak identified during post-static fire Falcon 9 rocket inspections. A new launch date for the fourth private astronaut mission will be provided once repair work is complete, pending range availability.

There a number of launches already scheduled for Florida in the next few days, so it could be that the launch of Ax-4 could be delayed by more than a few days.

Mexican officials demand investigation into Starship/Superheavy debris on its beaches

11:23 am

Mexican officials of the border state adjacent to Texas are now demanding an investigation into Starship/Superheavy debris that has been found recent on its coast, claiming SpaceX is “polluting Mexican beaches.”

Karina Lizeth Saldivar, the head of the Tamaulipas Secretariat for Urban Development and Environment, recently announced that they would be requesting that federal authorities in Mexico investigate the damages and potential damages that rocket fragments could cause.

According to Saldivar, the rocket pieces could pose a potential danger to locals and claimed that her agency would request a formal investigation by Mexican federal environmental agencies. It remains unclear if Mexico’s government could do anything about the issue.

Saldivar is a typical government apparachik. Rather than try to develop the beach area in Mexico that is close to Boca Chica and thus provides a great tourist spot for viewing launches, she instead can only whine and demand the government shut things down.

Meanwhile, the article notes that ordinary Mexicans aren’t complaining. Instead, they have been collecting the rocket pieces enthusiastically, with some making money by selling them as collector’s iten on social media.

Trump eliminates restrictions against supersonic flights over the U.S.

9:50 am

In an executive order released on June 6, 2024, President Trump eliminated the half-century-old regulations that forbid supersonic airplanes to fly over the land mass of the United States.

The Administrator of the Federal Aviation Administration (FAA) shall take the necessary steps, including through rulemaking, to repeal the prohibition on overland supersonic flight in 14 CFR 91.817 within 180 days of the date of this order and establish an interim noise-based certification standard, making any modifications to 14 CFR 91.818 as necessary, as consistent with applicable law. The Administrator of the FAA shall also take immediate steps to repeal 14 CFR 91.819 and 91.821, which will remove additional regulatory barriers that hinder the advancement of supersonic aviation technology in the United States.

This order makes sense for several reasons. First, the restrictions were always absurd. The sonic boom concern was always over-rated. Second, the concern increasingly doesn’t exist due to improvements in technology. In a flight test in January, the commercial supersonic airplane startup Boom Aerospace confirmed that its test plane broke the sound barrier three times and each time with “no audible sonic boom.”

Though Boom isn’t the only supersonic startup, it is far ahead of the others. It already has orders from United and Japan airlines for its Overture 80-passenger supersonic jet. This new Trump order will certainly help it attract investment capital, as well as more airlines willing to buy its planes.

Blue Origin again delays 2nd launch of New Glenn

9:37 am

According to a statement from David Limp, the CEO of Blue Origin, on June 9, 2025, the company has once again delayed the second launch of its new New Glenn rocket, pushing back from May to August.

New Glenn’s second mission will take place NET August 15th. Following in the footsteps of our first booster, we’ve chosen the name “Never Tell Me The Odds” for Tail 2. One of our key mission objectives will be to land and recover the booster.

The rocket’s first launch had occurred in January, and successfully placed its test payload in orbit as intended, though it was unable to land the first stage on its barge in the Atlantic. Blue Origin later said it was targeting May for the second launch, carrying NASA’s two Escapade smallsat Mars orbiters. With this new delay it is unclear what the payload would be.

According to this report, anonymous sources claim an August launch is unlikely and will likely slip to September. The company has a large backlog of launch contracts, including 27 for Amazon’s Kuiper constellation as well as a number for the military. The hope had been that it could ramp up its launch cadence in 2025 to meet those contracts.

Instead, Amazon has begun shifting some of its launch work to SpaceX’s Falcon 9. Its FCC license requires it to get 1,600 satellites in orbit by July 2026, and at present it only has sixteen in space. It can no longer wait for Blue Origin to dilly-dally along.

Considering the actual success of the first launch, it seems very puzzling for there to be a nine-month delay until the second launch, even with the failure to land the first stage. Was there some technical problems with the rocket that have not been revealed? It seems foolish to delay further launches in order to fix the landing of the first stage, since that has no impact on getting the customer’s payload into orbit. Wouldn’t it be better to fly again, test the landing again during flight, than sit on the ground looking at computer simulations?

It is also possible the company is still having production problems producing enough BE-4 engines for both ULA’s Vulcan rocket and its own New Glenn. Vulcan uses two per launch, and according to ULA Blue Origin has delivered enough to begin launching Vulcan as many as fifteen times before the end of this year. New Glenn uses seven BE-4s on its first stage. Could it be that Blue Origin wasn’t able to produce enough of these engines for this year’s New Glenn launches?

All this is speculation. What we do know for certain is that both of these companies continue to disappoint. The result is that for larger payloads the United States remains reliant entirely on SpaceX, a situation that is not healthy for the commercial and government satellite industry.

Scientists increase the odds asteroid 2024 YR4 will impact the Moon in 2032

9:10 am

Asteroid 2024 YR4 in 2032
Click for original image.

Using additional data obtained by the Webb Space Telescope, scientists have now refined the orbit of potentially dangerous asteroid 2024 YR4 and confirmed that while it will almost certainly not hit the Earth in 2032, the odds of it impacting the Moon have increased.

With the additional data, experts from NASA’s Center for Near-Earth Object Studies at the agency’s Jet Propulsion Laboratory in Southern California further refined the asteroid’s orbit. The Webb data improved our knowledge of where the asteroid will be on Dec. 22, 2032, by nearly 20%. As a result, the asteroid’s probability of impacting the Moon has slightly increased from 3.8% to 4.3%. In the small chance that the asteroid were to impact, it would not alter the Moon’s orbit.

The yellow line in the image to the right shows the present range of positions the asteroid could be in as it passes the Moon on that date. It is expected this range will be narrowed further when the asteroid flies past the Earth harmlessly in 2028.

If the asteroid should hit the Moon, the impact will provide scientists a great opportunity to learn more about asteroids and the Moon. If it should miss, it will then be essential to recalculate its orbit to see what will happen on later near approaches, whether the fly-by increased or decreased the chances of a later Earth impact.

SpaceX launches 23 more Starlink satellites

8:54 am

SpaceX this morning successfully launched another 23 Starlink satellites (including 13 with phone-to-satellite capabilities), its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its twelfth flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

72 SpaceX
33 China
7 Rocket Lab
6 Russia

SpaceX now leads the rest of the world in successful launches, 72 to 53.

SpaceX’s launch of Axiom’s AX-4 manned commercial mission to ISS, carrying government astronauts from India, Poland, and Hungary, has been delayed one more day to 8 am (Eastern) tomorrow due to weather issues.
